Bed of fossils (Sung to the tune of “Lake of fire” written by the Meatpuppets, performed by Nirvana)

The Science: Much of what we know about life long ago comes from our study of mineralized remains, or fossils. Fossils form when a living thing gets covered by soil or silt and its soft tissues are slowly replaced with minerals. Fossils are rare because most of the time soft tissue decomposes before it can be preserved. We usually think about dinosaurs when we think of fossils, but the limestone islands of the Bikini atoll are full of them as well!
